It could strengthen Naruto's relationship with Iruka. Since Naruto is the son of the fourth hokage, Iruka might see Naruto as an even more important part of the village and be even more protective. For example, he could be more involved in Naruto's advanced training.
Yes, in many fanfictions, Naruto is often depicted as a huge fan of the Fourth Hokage. After all, the Fourth Hokage is his father. Naruto grows up idolizing the Fourth Hokage's heroic deeds and wishes to be like him.
One interesting plot twist could be that the fourth hokage didn't actually die when he sealed the nine - tails in Naruto. Instead, he was trapped in a sort of limbo within Naruto's mind and could communicate with him at crucial moments, guiding him in ways that no one else could understand.
No. In the official Naruto series, Naruto is the son of the Fourth Hokage, Minato Namikaze. Fanfiction might play around with this concept for creative or alternate universe purposes, but it goes against the original lore.
In this fanfiction, Naruto might finally get the fatherly guidance he always craved from the Fourth Hokage. Maybe the Fourth Hokage would teach Naruto some long - lost jutsu that only he knew. It could also be a chance for Naruto to understand his father's sacrifices on a deeper level.
In this fanfiction, the plot might involve Naruto being tricked by an evil force into believing that the Fourth Hokage has some dark secrets. So he decides to fight him. It could also be a scenario where Naruto enters a different dimension where the Fourth Hokage is being controlled by an outside power, and Naruto has to free him by fighting. And during the fight, Naruto discovers new things about his father and his own abilities.
In most official Naruto lore, Naruto is not related to the Second Hokage. However, in fanfiction, anything can be possible. Some fanfic authors might create a story where Naruto is the Second Hokage's son for the sake of creating a unique plot twist or exploring different character relationships.
One option is a new, original villain created just for this fanfiction. This villain could be someone who wants to rewrite history and prevent the Fourth Hokage from ever becoming Hokage. So they target Naruto as he is the son of the Fourth Hokage. They might have some sort of time - traveling or reality - warping powers.
Naruto himself is often a popular character in these fanfictions. Since he is the main character of the original series and has a connection to the Fourth Hokage as his father, his presence adds depth to the story. Kakashi is also common. His relationship with the Fourth Hokage was that of a student - teacher, and it can be further explored in fanfictions.
If Naruto was the Third Hokage's son in fanfiction, his social standing in the village might be different. He could have had more privileges and perhaps less of the ostracism he faced in the original story. The Third Hokage might have been more directly involved in Naruto's upbringing, which could have led to Naruto being more trained in traditional village techniques earlier.
